Aerobic And Anaerobic Conditions

SummaryThe use of wastewater for irrigation and animal manure as fertilizer can cause transmission of intestinal pathogens, conditions frequently observed in Low- and Middle-Income Countries (LMICs). Here we tested the ability of Salmonella to grow in the fecal matter; we inoculated freshly isolated Salmonella strains (from chickens) in chicken fecal matter and incubated for 24, 48 and 72 hrs under aerobic and anaerobic conditions. We found that both Salmonella and E. coli multiplied massively in fecal matter outside a host for 72 hrs, being their growth higher in aerobic conditions. Our results have critical implications in waste management, as we demonstrate that aerobic treatments may not be the best to reduce the number of Salmonella in the environment.

Municipal solid waste management is a critical factor in sustainable development. This task is the most important priority of state policy at the present time. The purpose of the study is to review the experience of leading countries in the field of economic incentives for the rational management of municipal waste. The study examines the experience of Germany and Croatia in the implementation of a depository-pledge system for handling containers and food packaging. As a result, the study examines the prospects and ad-vantages of using this system in the Russian context.

Abstract The aim of European Union policy is to implement the principles of sustainable development, in which particularly important are: environmental protection and rational management of resources. Major role is given to waste management and appropriate prioritization of activities in this area. The main goal of waste management is prevention, minimization and elimination of wastes “at source”, as well as encouraging efficient use of natural resources through recovery and recycling of waste. Storage process should be minimalized over the years until the complete elimination. As shown by statistics data, unfortunately in Poland, the process is very slow. The analysis of the data provided by the Central Statistical Office (CSO) over the last thirteen years shows a significant increase in the level of recovery and recycling of municipal waste. All together it was 11.654 million Mg of municipal waste collected in 2016. Wastes selected from municipal waste (paper, glass, plastics, metals) accounted for only 25.2% (2.942 million Mg), and mixed waste accounted for 74.8% (8.712 million Mg). In 2016 the recycling rate was 27.83%, composting or fermentation – 16.22%, 19.44% of municipal wastes are subjected thermal transformation and the storage level is 36.51%. Landfilling is still the most common form of municipal waste disposal.

Fossil Fuel Emissions

Learning or material on processing waste to produce electricity is needed because demand for electricity increases, while uncontrolled trash. Uncontrolled increase in litter causes uncontrolled pollution in the air anyway. Coupled with the fossil fuel emissions that are contributing to pollution and environmental pollution are greatest. Processing environmentally friendly fuels such as waste must be developed. Learning about the waste that exists today only still lacking and is still text-based or in book form. This leads to a lack of public interest to learn the material on waste management. The existence of this application, a solution to these problems. This application is designed in the form of exciting multimedia learning so as to increase public interest in the field of waste management. In addition in the form of multimedia, this application is also easy to operate, because the location and navigation menu uncomplicated. Waste processing in this application refers to the existing landfill gas systems in Power Plant Waste (PLTSa) Bantargebang.

Medical waste is waste generated in medical and health institutions and poses a risk to those who created, packaged, stored, transported, treated and performed the disposition. The management of medical waste is an organized process that consists of five elements: separation; identification; handling; treatment and disposition. Clinical waste is defined as 'any waste which consists wholly or partly of human or animal tissue, blood or other body fluids, excretions, drugs or other pharmaceutical products, swabs or dressings, syringes, needles or other sharp instruments'. This type of waste may prove hazardous to any person coming into contact with it unless it is rendered safe. Waste is defined as 'hazardous' when the waste itself or the material or substances it contains are harmful to humans or the environment. The other main waste stream is known as offensive waste, which primarily contains waste that is considered unpleasant due to its appearance and smell, for instance incontinence waste. Management of whole medical waste requires strict control and monitoring from the spot of occurrence, until its final storage. Each health institution should tend to reduce the amount of medical waste, meaning to organize and control the generating of the bio-hazardous waste as well as to organize and control the action of collection, transportation and destruction of the waste.

Acid Whey

Anaerobic digestion (AD) is widely considered a more sustainable food waste management method than conventional technologies, such as landfilling and incineration. To improve economic performance while maintaining AD system stability at commercial scale, food waste is often co-digested with animal manure, but there is increasing interest in food waste-only digestion. We investigated the stability of anaerobic digestion with mixed cafeteria food waste (CFW) as the main substrate, combined in a semi-continuous mode with acid whey, waste bread, waste energy drinks, and soiled paper napkins as co-substrates. During digestion of CFW without any co-substrates, the maximum specific methane yield (SMY) was 363 mL gVS−1d−1 at organic loading rate (OLR) of 2.8 gVSL−1d−1, and reactor failure occurred at OLR of 3.5 gVSL−1d−1. Co-substrates of acid whey, waste energy drinks, and waste bread resulted in maximum SMY of 455, 453, and 479 mL gVS−1d−1, respectively, and it was possible to achieve stable digestion at OLR as high as 4.4 gVSL−1d−1. These results offer a potential approach to high organic loading rate digestion of food waste without using animal manure. Process optimization for the use of unconventional co-substrates may help enable deployment of anaerobic digesters for food waste management in urban and institutional applications and enable increased diversion of food waste from landfills in heavily populated regions.
